Steel Core Designs is showcasing a whole range of Thunderbolt sniper rifles
during IDEAS 2014, all based on the SC-76 7,62 x 51mm sniper rifle. The
whole range uses a rugged, high tensile steel 4-lug bolt, incorporating
a new innovative firing pin system. The short firing pin travel enables
a very fast 'lock time' (time from pulling the trigger to striking the
primer) of around 1.5 milliseconds, vital for making a crucial shot with
a long barrel rifle.

SCD Thunderbolt
heavy recoil plate system is located into both the action body and rifle
stock; this is essential for rifle accuracy and greatly assists recoil
management. Low friction, wear resistant VDP coatings, reduces the need
for lubrication making these weapons ideally suited for the harsh gritty
conditions experienced in the deserts; damp dirty conditions of forest
and jungle; performing equally well in extreme hot and cold conditions.

The rifle safety lever is incorporated in the trigger mechanism for
right handed operation; optionally the safety can be readily adapted
for left handed operation when required.

The most critical link between the shooter and the rifle is the trigger.
All SCD triggers are designed with two stage operation, 1st and 2nd
pull, factory set to a 1.5 kg pull weight for safety, with a crisp,
predictable release. Maintenance requirement is minimal, but should
the need arise as with all of our designs, it is easy to remove and
replace for cleaning.

The main Picatinny scope rail is available with a parallel or angled
option to suit the customer requirements. Additional Picatinny rails
for the use of ancillary items such as laser illuminators and designators
can be easily accommodated as user options. SCD barrels are produced
to a very high quality match grade specification, fluted for improved
heat dissipation and rifle balance. The barrel is threaded at the muzzle
for easy attachment and detachment of the muzzle brake or suppressor.

The SCD designed bipod is fully height adjustable and fits to the forend,
maintaining the optimum pivot position around the centreline of the
rifle. Thunderbolt's quid release system ensures no tools are required
to attach and detach the bipod.

SCD highly efficient muzzle brakes are a standard fitment to all SCD
rifles and greatly reduce recoil; this further enhances the shooting
experience and improves accuracy.

All SCD rifles feature a folding butt stock as standard for easy bore
sighting, cleaning, maintenance and transit. It is also adjustable for
length with spacers and incorporates a quick deployment mono pod, fully
adjustable with thumbwheel fine adjustment.

Steel Core Designs'
unique ambidextrous economically designed rifle stock makes the Thunderbolt
a pleasure to use; providing greater shooter comfort, reduced recoil
and absorbing vibration; this assists in the quick re-acquisition of
target from shot to shot. The innovative use of materials in the stock
design such as rubber and aircraft specification alloys, have been proven
in extremes of hot and cold operational environments to maintain operation,
strength and stability.

Thunderbolt sniper
rifle is available in three variants.The SC-76 7.62 x 51 NATO with 10
